The enclosure shall be designed for wall mounting and shall include provisions to accept a floor support frame that may be specified when a wall structure is questionable or inadequate to support the switchgear. The switchgear shall be constructed for connection to the utility system with noninsulated two-hole NEMA Standard connectors and/or separable insulated connectors as described in IEEE Standard 386—latest revision (separable insulated connectors [and loadbreak inserts when required] shall be supplied by the user). The switchgear shall be designed for and contain a three-pole, group-operated interrupter switch that includes an external nonremovable side-mounted operating handle. The operating handle shall be padlockable in the open or the closed position and shall include provisions for key interlocks. A door safety barrier shall be provided inside the door on the switch compartment as recommended in IEEE Standard C2 (National Electrical Safety Code) Rule 381G. Tamper resistance shall meet the Enclosure Security requirements of IEEE Standard C57.12.28 (Pad-Mounted Equipment—Enclosure Integrity). Together, the tamper resistance and the door safety barrier shall resist unauthorized entry, protect authorized and unauthorized persons, and provide positive safety features when installed in areas accessible to the general public. The switchgear shall be constructed for indoor/outdoor installation in areas subject to precipitation and in areas with windblown contamination. The equipment shall be “air-insulated” and completely assembled prior to shipment. Enclosure Construction The enclosure shall be tamper-resistant, all-welded construction utilizing 11-gauge minimum sheet steel. Single and double 90-degree bends shall be used as necessary to assure strength and rigidity. The enclosure top shall be cross-kinked to provide watershed and rigidity. The switch compartment access door shall be furnished with a stainless steel door holder that will latch the door open 100 degrees and 140 degrees and resist accidental closing. The door shall be provided with provisions for padlocking and a recessed penta-head (or hex-head) security bolt to prevent unauthorized entry (coordinated to prevent installation of the padlock until the security bolt is tightened when closing the door(s) and to prevent a wrench from operating the security bolt until the padlock is removed when opening the door(s)). The security bolt shall be made captive with a stainless steel washer compressed to an oval shape to severely discourage removal. Hinges shall be stainless steel (with stainless steel pins not less than 0.3125-inch diameter) and shall be welded to both the enclosure and the door to maintain door alignment for the life of the equipment. The enclosure shall be nonventilated to minimize the entrance of airborne contamination, insects, rodents or reptiles. The protective finish shall include necessary grinding, cleaning and phosphatizing, two-component rust-inhibiting epoxy primer and a Pad-Mount Green two-component polyurethane top coat finish—Munsell color 7GY 3.29/1.5 (or Optional Grey—Munsell color 5BG 7.0/0.4). The primer and top coat shall be electronically monitored during application to insure proper ratio and mixing of each component. Total average thickness of paint (after curing) shall be not less than 5 mils. The protective coating shall meet the Enclosure Coating System requirements of IEEE Standard C57.12.28 (Pad-Mounted Equipment—Enclosure Integrity). Removable lift provisions, adequate to withstand handling with normal utility equipment, shall be provided on the outside of the enclosure. Threaded openings for lift provision bolts shall be blind holes to prevent the entrance of wire or other foreign objects into the enclosure when lift provisions are removed. Four threaded openings for attachment of a floor support frame (to provide additional support when a wall structure is questionable or inadequate) shall be provided on the bottom of the enclosure. The threaded openings shall be blind holes and shall be unpainted internally to provide a ground for the floor support frame that may be installed. When specified, an 18-inch (alternate 24-inch, 30-inch, 36-inch or 42-inch) high floor support frame shall be supplied bolted in place with stainless steel hardware. The floor support frame shall be all-welded construction utilizing 11-gauge minimum sheet steel formed to assure strength and rigidity. The two ground lugs specified for the bottom of the enclosure shall be installed on the floor support frame not more than 6 inches from the original location. The protective coating of the floor support frame shall meet or exceed the coating requirements specified above for the enclosure.
